1993 Kenney Res. Channel Catfish Study Report ;' <br />Page 13 <br />further downstream. These movements appeared to coincide to times <br />when the hydropower plant at the reservoir would accidently <br />shutdown, resulting in severe flow fluctuations. The greatly <br />reduced hoop net catfish catch in the upper reach may be the result <br />of these problems at the power plant. However, contrary to this <br />notion is the July electrof ishing catch which was higher in the <br />upper reach than in the lower reach. While a comparison of dates <br />when the power plant shut off to catfish sampling dates could help <br />explain the catch results, this matter is of little further <br />consequence since the power plant problem has been fixed. <br />Other fisheries biologists -and anglers provided additional <br />potential sources of information for the recovery of marked channel <br />catfish in the White River below Kenney Reservoir. There were no <br />reports of marked channel catfish from biologists from the U.S. <br />Fish and Wildlife Service or the Utah Division of wildlife <br />Resources. Two anglers did report catching stocked (adipose fin <br />clipped) catfish from the river. One angler was questioned by this <br />author and reported catching two adipose fin clipped catfish <br />immediately below the dam. These fish were of the appropriate size <br />to be stocked fish. The other report came from an angler who was <br />questioned by a District Wildlife Manager and reported catching two <br />adipose fin clipped fish about 18 miles below the dam. No size <br />information was available for the later report. Neither report <br />could not be substantiated further by additional information or by <br />another person. Both reports are viewed with some suspicion since <br />the adipose fin clip mark is difficult to casually notice. <br />VII. Recommendations <br />Sampling should continue according to the same basic plan as was <br />conducted in 1993 with only minor changes. The major components of <br />the plan for 1994 are: <br />Reservoir: <br />1) Sample for approximately two weeks during the months of <br />July and August. Water temperatures will be warmest in <br />Kenney Reservoir during these months, so fish will be <br />active and should show growth since 1993. <br />2) Sampling gear will be gill, trammel, and hoop nets. In <br />a departure from 1993, electrof ishing will not be used on <br />the reservoir since zero catfish were captured by this <br />technique. The additional time will be used to work (set <br />and pick) nets more frequently and, if possible, place <br />more gill nets overnight than were used in 1993. At <br />most, four gill/trammel net sets were placed overnight in <br />1993 because of the length of time it took the following <br />day to remove fish. Trammel nets will be judiciously <br />
